What you think we wearing black for

The black Jay and his crew wears is indicative of a well-organized family that watches over each other. Similar to the FBI or CIA, Jay has his crew in black. As he already said before he wears black a lot!

There’s a double meaning. You wear black to kidnap somebody in the night, but you also wear black to a funeral. To Wayne: Jay’ll kidnap your family and murder you in front of ‘em.
